GPT-5.6 登陆 Kiro，为开发者提升性价比

T he GPT‑5.6 model family is now available in Kiro, a software development agent that brings engineering rigor and quality to AI-native coding at scale. For Kiro users, the update brings OpenAI’s latest flagship model series, including Sol, Terra, and Luna, into the development workflows where teams plan, build, review, and test software. Together, these models can help developers produce higher-quality code with fewer iterations and better value per token.

GPT‑5.6 delivers more useful work from every token, with stronger performance per dollar and on-demand capability for complex tasks. In Kiro, developers can apply these capabilities to long-running development work grounded in their requirements, codebase, and team standards.

Kiro turns high-level intent into clear requirements, technical designs, and executable tasks. This structured context helps GPT‑5.6 understand what a team is building, how the system should work, and what the final implementation needs to accomplish.

With GPT‑5.6 in Kiro, developers can:

• Turn product ideas and requirements into structured implementation plans.
• Complete complex, multi-step coding tasks with greater consistency.
• Bring structure to AI coding with spec-driven development.
• Work with context from across their codebase and established team standards.
• Review and refine the model’s work at key checkpoints before changes are implemented.
• Check correctness of implementation using property-based testing.

OpenAI and AWS have also worked together to optimize the Kiro environment and OpenAI models.Testing found that on Terminal-Bench 2.1, GPT‑5.6 Terra completed successful tasks in Kiro at roughly 82% cost reduction. Kiro’s spec-driven approach grounds the model in clear requirements, technical designs, and task context from the start, so it arrives at working solutions faster, with fewer missteps along the way. For developers, that means more finished work, less wasted effort, and better value from every coding session.

“We are always looking to make the latest foundation models available to developers and expand their options to accelerate AI-native development using Kiro. We are excited to add the GPT‑5.6 family of models to power complex and long-running development tasks in Kiro.”

—Swami Sivasubramanian, Vice President, Agentic AI, AWS

“By bringing the GPT‑5.6 family to Kiro, developers gain more room to match intelligence, speed, and cost to each stage of the software development lifecycle. Together with AWS, we’re helping teams get more from every dollar they invest in AI while moving faster when time matters.”

—Colleen Kapase, Vice President of Strategic Global Partnerships and Ecosystems, OpenAI
